Command: H
Mnemonic:

EXCT_epoll (event poll)

Parameters:

[1..119] corresponding to event selection codes STOP..STARTCPL as listed below:

Description:

Requests return of selected event condition history since last poll. If selected event has

had an occurrence since last computer poll (RS232 parser, beware of intermingled requests for this
information) then will return a true (1) value. If no events at all or since last poll then will return false (0).


Returns:

[RZCD_AOK][0 or 1] if proper event id [1..119] was sent.

[RZCD_ILDV] if improper value for parameter arguments.

[RZCD_ILSN] if too many arguments, wrong delimiters, etc..

NOTE: Certain events may be disallowed depending on whether or not sequencing is enabled
in the instrument.


Command: I
Mnemonic:

EXCT_etrig (event trigger)

Parameters:

[1..119] corresponding to event selection codes STOP..STARTCPL as listed above

Description:

Causes the selected event to be triggered or made to occur such that any other

system logic can detect it and then perform as designed. I/O can respond to events, the auto-matic
process sequence system can respond to events, etc.

Returns:

[RZCD_AOK] if proper event id [1..119] was sent.

[RZCD_ILDV] if improper value for parameter argument.

[RZCD_ILSN] if too many arguments, wrong delimiters, etc..

NOTE: Certain events may be disallowed depending on whether or not sequencing
is enabled in the instrument.

Command J

(J)

Read I/O Information. These commands will read the states of the remote inputs and relays, status
codes, softnodes, counter values.

Command: J
Mnemonic:

EXCT_ioexm (I/O exam)

Parameters:

[0..71, 72..128, 150..157, 300..399, 400..409]

Description:

Requests a read of state of I/O nodes which correspond to the identifier code (0..128,

150..157, etc..). A return of non-zero indicates TRUE or active. A return of 0 indicates FALSE or
inactive. Scalar types can return numeric values between 0 and 255 (such as bit maps,
counters,etc). These values are only usable (dynamically updated with new information) if the
corresponding node identifier is actually being used within the live (active) I/O program. The state
